The thickness I use is 3/8. That together with the gasket I use puts you flush with the gutter. Very light and very strong. This is a pic of the fishbox, large square and small rectangle. On the small the hatch is upside down that is why it looks odd. Big rectangle not shown. SG, on this I have a gasket face that a 5/16 gasket goes on and that together with the layup I outline make everything sit flush. Gasket comes from Home Depot believe it or not. Haven’t source a bulk supplier and they are not cheap. I make the hatch 3/8 smaller than the gutter face which give you 3/16 gap. That allows either a piano hinge or conventional hinge to be used. If you want recesses for hinges just put a block out in the mold in that area. That all the secret sauce Hope that helps!

The reason veil is used in mold/plug building is to prevent larger cloths from transferring a pattern over to the final product.

If you look close you can see a chopped strand mat pattern on some boats gel coat. It’s likely their initial layer used something like 1.5oz csm as their first layer under the gel coat. Veil prevents print through from happening.
